It will "crash" for the same reason as plasmashell. Actually it aborts in Qt when trying to create a GL context for the QML scene (that powers the tabbox) and apparently when checking for the primary screen. There're not enough backtrace symbols to say *what* in Qt triggers the abort, but if you run kwin from konsole (or xterm) you should get an abort message that will tell us what's wrong here. On a wild guess, please attach the output of xdpyinfo -queryExtensions Please provide a better backtrace and the output requested in comment #1 Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days, the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please set the bug status as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone! Sorry and you're right, I haven't delivered any input in the meantime (wow, 3 years now). The original problem was recreated on an Apple-G5 with ATI graphics-adapter and the Radeon-driver for X11. There was a problem with the MESA libraries so that GL was not supported on Big-Endian machines (the details can be found here -> https://lists.freedesktop.org/archives/mesa-commit/2015-July/057473.html). In the meantime, that has been fixed and now I am able to run GL also on the Apple-G5 with ATI Radeon adapter ... but I currently don't use that G5 but another one with NVIDIA-Nouveau driver. At a first try kwin starts and doesn't crash on my current G5 with NVIDIA, but now I see that I reported we'll only have the problem if pressing Alt-Tab. You know, Fedora Core 25 is the current and recommended version for Apple-G5 systems (not Fedora Core 22). What about if you just close this ticket and I open another one in case I still see the problem on a newer version? No problem, thanks for the update! |
